1.形容词比较级的构成。①单音节和少数双音节形容词、副词的规则变化情况：a.在原级的词尾加-er变为比较级eg.short(原级)---shorter(比较级)long(原级)---longer(比较级)b.如原级以e结尾，则比较级只加-r。eg.large---largernice---nicerc.如原级以“辅音字母+y”结尾，要将y改为i，再加-er。eg.busy---busiereasy---easierd.原级以重读闭音节结尾，而且末尾只有一个辅音字母(不含字母组合er等)，要双写这个辅音字母，再加-er。eg.fat---fatterbig---bigger②大多数双音节和多音节形容词、副词的规则变化，是在原级前加more变成比较级，加most变成最高级。eg.beautiful(原级)---morebeautiful(比较级)interesting(原级)---moreinteresting(比较级)③有少数形容词,副词的比较级和最高级是不规则的。这些单词的变法需要大家识记。eg.good---betterbad---worsemamy/much---morelittle---lessfar---farther/further2.形容词比较级的用法和相关句型。①表示两者“相等”用“as+形容词原级+as+比较对象”。eg.Heisastallashismother．Englishisasinterestingasmath.②表示“不如”或“不相等”用“not+as／so+形容词原级+as+比较对象”。eg.Itisnotso／ascoldtodayasyesterday．Jackisnotso/astallasTom.③表示倍数，如“一半／两倍/3倍／4倍／……”等用“half／twice／three／four／…times+as…as…”结构。eg.Istudytwiceashardasyou．Thisroomisthreetimesaslargeasthatone.④用“形容词比较级+than引导的从句”进行两者的比较。eg.Theearthisbiggerthanthemoon．Thisdressismoreexpensivethanthatone.⑤强调比较级超出比较程度时，形容词的比较级前可用much，far，alot，still，no，alittle，even，any,等状语来修饰。eg.MybrotherismucholderthanI.Thisbikeisfarbetterthanthatone.⑥由and连接同一个形容词的两个比较级，可以表示“越来越……”。eg.I’mgettingfatterandfatter．IthinkEnglishisbecomingmoreandmoredifficult.⑦用“the+比较级…+the+比较级…”，表示“越……就越……”。eg.Themoreyouread，themoreknowledgeyouwillget．Thelessjunkfoodyoueat,thehealthieryoufeel.一写出下列形容词的比较级1.small2.high3.nice4.wide5.heavy________________6.early7.hot8.big9.low10.slowly11.expensive12.little_______________13.difficult14.many/much15.old___________16.old17.far18.good/well19.bad/badly______________20.awful21.clean_________________22.clever23.beautiful24.cheap_________________25.cold________________26.colorful_______________27.cool_________________28.crowded29.dangerous30.delicious31.dirt32.fantastic33.friendly34.hard35.hungry36.late37.lazy38.quiet39.smart40.tall41.thin42.ugly43.few44.long________________45.happy________________二用所给词的适当形式填空。1.Janehaswaterinthebottle.MaryhasthanJane.Carolinehastheofall.(little)2.Theearthis,thesunisthantheearth.(big)3.Bobis(young)thanFredbut(tall)thanFred.4.Tomisnotas(tall)asJack.5.Whichis(heavy),thisboxorthatone?6.Anorangeisalittle(big)thananapple,butmuch_____________(small)thanawatermelon.7.Myroomisnotas______________(big)asmybrother’s.8.--Howdifficultisphysics?--I'mnotsure.--Isit_______________(difficult)thanmath?--Idon’tthinkso.9.--Annieplaysthepianovery(well).--Sueplaysit(well)thanAnnie.10.Hermotherisgetting(fat)and＿＿________(fat).11.Ithinkit’stooexpensive.I’dlikea(cheap)one12.Hecomestoschoolmuch(early)thanI.13.Thisbookisnotas(interesting)asthatone.14.Yourclassroomis(wide)an(bright)thanours.15.Practiceas(much)asyoucan.16.The(much),the(good).17.NowadaysEnglishis(important)thananyothersubject,1think.18.Mostofthestudentsthinkalionismuch____________(dangerous)thanabear.19.Shewillbemuch_______________(happy)inhernewclass.20.Theshortoneis________________(useful)ofthefive.21.Hissisteristwoyears________________(young)thanhim.22.Thisruleristwiceas_______________(long)asthat.23.The________________(cheap)bagsareusuallythebestones.24.Gold(黄金)ismuch_________________(expensive)thaniron(铁).25.Theboyisnotso_________________(interesting)ashisbrother.26.Jacksings____________(well),hesings___________(well)thanTom,butMarysings_____________(well)inherclass.27.Ofthethreegirls,IfindLucyis_____________(clever).28.Ofthetwogirls,IfindLucythe____________(clever).29.Theboyisnotso_____________(interesting)ashisbrother.30.Dicksings___________(well),shesings___________(well)thanJohn.三单项选择。1.--Sheis______thanhermother.--Hermotherisalsobeautiful.A.beautifulB.beautifulerC.morebeautifulD.mostbeautiful2.--Ourschoolistheirs.--Whatabigone!A.asfivebigasB.asfivetimesbigasC.asbigasfivetimesD.fivetimesasbigas3.--Doyoualwaysgetupasasyoubrother?--Notalways.A.earliestB.earlierC.theearliestD.early4.--Theearthis______themoon.--Ialsosawitonthenewspaper.A.as49timesbigasB.49timesasbiggerasC.49timesasbigasD.asbigas49times5.--Howtimeflies!--Yes,shelooks______thanbefore.A.themoreolderB.veryolderC.mucholderD.moreolder6.Wouldyoupleasesayit?－－Istillcan’tfollowyou.A.moreslowB.muchslowC.moreslowlyD.muchslowly7.Heis________morebeautifulthanI.A.tooB.enoughC.muchD.very8.Thisbookis_______thatone.A.asbetterasB.asgoodasC.asbestasD.aswellas9.--Itlookslikethatheisas______asyou.--Oh,no.Heis_______thanI.A.tall,alittletallB.taller,alittletallC.tall,alittletallerD.taller,alittletaller10.--Thanksfortakingcareofthegarden,itisbecoming______.--Youarewelcome.A.morebeautifulandmoreB.morebeautifulandmorebeautifulC.moreandmorebeautifulD.morebeautifulandbeautiful11.Theboxis______heavy.Ican’tmoveit.A.muchB.moreC.enoughD.too12.Herbrotheris_______thanshe.A.sevenyearolderB.sevenyearolderC.sevenyearsoldD.sevenyearsolder13.The_________youstand,the_________youcansee.A.high;farB.higher;fartherC.highest;farthestD.morehigher;morefarther14.YoushouldstudyEnglishhard,becauseit’sgetting_________inourcountry.A.moreandmoreimportantB.moreimportantandmoreimportantC.importanterandimportanterD.importantandimportant15.--Theycompeted（比赛）toseewhocouldwork______.--Wish
